This 3D-printed sculpture is a three-dimensional materialization of President Obama’s voic...

It seems there's little that you can't create with 3D printing; we've recently seen lingerie, guns, rocket engines, musical instruments and even rooms. French artist Gilles Azzaro, however, uses the technology to capture something much more abstract. His 3D-printed sculptures of voice recordings resemble alien landscapes, with high and low tones represented as peaks and troughs. Instead of only hearing the rich tones of Barack Obama's State of the Union speech, you can see them too, in Azzaro's latest sculpture entitled "Next Industrial Revolution."  Read More

This artificial muscle-driven heart pumps human urine and will be used to power the Ecobot...

It's strange to wrap one's mind around the idea of human pee powered robots, but that's exactly what a group of UK researchers are attempting to create. Mimicking the human heart, their latest innovation is a heart pump with artificial muscles that aims to deliver human urine to their latest generation of Ecobots – a self-sustaining robot that runs on all manner of waste matter collected from its environment.  Read More

The spiky surface of black silicon shred certain types of bacteria, offering the potential...

Originally discovered by accident in the 1980s, black silicon is silicon with a surface that has been modified to feature nanoscale spike structures which give the material very low reflectivity. Researchers have now found that these spikes can also destroy a wide range of bacteria, potentially paving the way for a new generation of antibacterial surfaces.  Read More

Scientist have created a new form of matter by coaxing photons to interact with each other...

Scientists from Harvard and MIT have jointly demonstrated that, in specific conditions, photons can be made to interact with each other and form molecules. Such groupings of photons, dubbed “Photonic molecules”, constitute an entirely new form of matter, which until recently was purely theoretical. Combining the properties of light and those of solids, in terms of physics this new form of matter is not unlike a certain material that millions of Star Wars fans are already well familiar with. Lightsaber material.  Read More

A model of a high altitude aerial power plant that harvests both solar and wind energy and...

Harvesting power from the wind and the sun is nothing new. We've seen flying wind turbines and solar power plants that aim to provide clean renewable energy. UK-based New Wave Energy has a bolder idea in the works. The company plans to build the first high altitude aerial power plant, using networks of unmanned drones that can harvest energy from multiple sources and transmit it wirelessly to receiving stations on the ground.  Read More

Figure of a plasmonic metasurface hologram of the word 'PURDUE' that is about the width of...

Holography is one of the more dramatic forms of photography, in which a three-dimensional image is stored on a photographic plate in the form of interference fringes. Researchers at Purdue University in Indiana have developed a different approach, in which a 3D image is stored in a structure of thousands of V-shaped nanoantennas etched into an ultrathin gold foil. The new approach dramatically shrinks the size of a hologram, potentially enabling photonic and plasmonic devices and optical switches small enough to be integrated into computer chips.  Read More

The Selfmade cheese, by Christina Agapakis and Sissel Tolaas, is part of Grow Your Own ......

We're no strangers to unusual food here at Gizmag, but this latest culinary masterpiece is probably the most unappealing treat we've yet come across. Dubbed Selfmade, the cheese in question is made from human bacteria which derives from samples taken from people's armpits, toes, and noses.  Read More

The 3D-printed vertebral body next to the original unprepared and erroneously labeled plas...

Access to rare fossils is limited, potentially putting a go-slow on their study, while sharing them around increases the risk of damaging them. Researchers at Berlin's Charité Campus Mitte have combined data from computed tomography (CT) scans with 3D printing technology to make it possible to print any number of accurate 3D reproductions of fossilized bones, without any adverse effect on the originals.  Read More

The Universe is big, and so is the challenge of understanding its large-scale structure (P...

Our knowledge of the large-scale structure of the Universe is gradually taking shape. However, our improved vision is mostly being statistically squeezed from huge data sets. Working backward from a statistical analysis to a putative fact about the (singular) Universe, to which statistics do not apply on a cosmological scale, is a dicey business. A case in point is a recent look at the biggest known structures in the Universe – large quasar groups.  Read More

This image shows two electrodes connected via an external voltage source splitting water i...

Photoelectrochemical (PEC) cells can use sunlight to sustainably split water into hydrogen and oxygen, but efficient PEC materials tend to corrode rapidly in use. A Stanford research group has been studying this problem, and has found that depositing a thin layer of nickel atoms on a silicon PEC electrode allows it to operate for over 80 hours with no sign of corrosion.  Read More
